Answer:
Step-by-step explanation:
The gift wrap needed by Damarcus = total surface area of a rectangular box = 1,048 in.².
<h3>What is the Total Surface Area of a Rectangular Box?</h3>
Total surface area (TSA) = 2(wl+hl+hw), where:
- l = length
- w = width
- h = height of the box.
The amount of gift wrap needed to cover the whole box = total surface area of the rectangular box
l = 20 in.
w = 8 in.
h = 13 in.
Plug in the values into the formula for total surface area of a rectangular box:
TSA = 2(8×20 + 13×20 + 13×8)
TSA = 1,048 in.²
Therefore, the gift wrap needed by Damarcus = total surface area of a rectangular box = 1,048 in.².

Step-by-step explanation:
Answer:
The answer to your question is y = x - 5
Step-by-step explanation:
Data
Point = (4, -1)
line ║ to y = x - 1
Process
1.- Find the slope. The slope is the coefficient of the x.
y = 1x - 1
slope = m = 1
2.- Identify the values x1 and y1
x1 = 4 y1 = -1
3.- Find the equation of the line
y - y1 = m(x - x1)
-Substitution
y + 1 = 1(x - 4)
-Solve for y
y + 1 = x - 4
y = x - 4 - 1
-Result
y = x - 5
Answer:
z = 9
Step-by-step explanation:
To find the solution, undo what is done to z. You can start by adding 27 to both sides of the equation.
6z -27 +27 = 27 +27
6z = 54 . . . . . simplify
Now, you can divide by 6 to make the coefficient of z be 1.
6z/6 = 54/6
z = 9 . . . . . . . simplify
